MANUAL MOTOR.

citizen of the United States,residing at Coll* legeville, in the. county of Montgomery and State ofPennsylvania, have invented a new and useful Manual Motor, of which the folmanual motors or propelling mechanismA for vehicles, etc. Y .Y l The object of the `present invention is to .improve the construction of manuallygoper-` able propelling mechanismand to provide 'a simple, practical, and -eicient construction, designed primarily for propelling vehicles,

boats, and other conveyances, and capable also of being advantageously `employed for operating various mechanisms.

A further object of the invention to provide propelling or motormechanism of this character, equipped` lwith a rocking chair `orseat, and capable ofi-responding to the slightest movcment'of the same in either direction, whereby the mechanism may be conveniently operatedwith along or short stroke by the weight of a person, with little exertion.

It is also an object of the -invention to` proi videan operating leverarranged in conf venient position with relation to the rocking f chair orseat, and capable of operation'lnde-` pendently thereof, and also of being actuated in Aconjunction therewith, and of assist-` L ing and facilitating the movement of the' rocking chair: l i

invention yconsists yin the construction-and Vvarious changesI in the form, proportion',y

l.` i Fig. 3 isa vertical longitudinal sectional view taken substantially on the line 3 3 of ig. 2; F igfl is a plan view of the propelling mechanism, partly in section, and partly .broken away. L Fig. 5 is a horizontal sectional view, taken substantially on the ,s line of Fig. 3. The invention relates to improvements in Fig. 6 is a vertical` sectional view illustrating the construction of tion, the manually operable motor or propelling mechanism is shown applied to a rockermobile, but the manual motor or propelling mechanism may be advantageously employed Ifor operating various machines and devices.

The rockermobile comprises' in its construction a frame l provided with front and rear axles 2 and 3, on which are mounted front and rear wheels and. The rear wheels are iixed to the rear axle, which isjournaled in suitable bearings of the frame of the vehicle, and isdriven by the pro pelling mechanism.

The machine, in practice, is designed to'be equipped 4,with suitable steering gear, Vand,

it may-"be made in the form of a toy automobile, as indicated in the accompanying drawings, orbe constructed in any other ,Y s desired manner, as the propelling mechalVith theseand other objectsin viewA the i nisniwill be found both useful and advantageous for propelling various kinds of ven hicles.

The reargaxle has keyed `orgotherwise secured to it a sprocket pinion 6, which is connected by a sprocket chain 7 with a sprocket wheel S of a transverse shaft 9. The transverse shaft 9, which extendsacross and is journaledA in suitable bearings l0 of a casing ll, is connected by variable speed gearing with a transverse driving shaft l2. `While it is preferable to employ sprocket gearing for connecting the transverse shaft 9 with the rear axle, any other suitable gearing may be employed, and the said transverse shaft 9 may be gearedwith various machines and devices `for operating the same. "The driving shaft extends across and is journaled in suitable bearings 13 of the casing 11, and while ball bearings are shown, thev shaftsV may, of course, vbe

mounted in any desired manner. v The variable speed gearmg, may be of any preferred' construction, 1s
